If the term "social justice warrior" is being used in a pejorative sense, then no, of course not.
If it is being used in the sense of "someone who longs for a more just society and is willing to make sacrifices to help bring this about" then yes, to an extent. When you're Aspie, most current societies are going to force sacrifices upon you anyway, so why not put them to good use?
